Railway Noise Prediction — Rail Infrastructure Noise Assessment Software

Railway projects — metro systems, commuter rail, high-speed rail, and light rail — generate significant noise and vibration impacts on communities along the alignment. Rigorous noise assessment is required at the feasibility, EIA, detailed design, and operational monitoring stages of every major rail project. SoundPLAN provides comprehensive railway noise prediction using all internationally recognised calculation methods.

In Asia and the Middle East, rail network expansion is accelerating rapidly — from metro systems in Bangkok, Kuala Lumpur, Manila, Jakarta, Riyadh, and Dubai, to high-speed rail projects across India and Southeast Asia. SoundPLAN Asia supports rail project developers, concessionaires, and their environmental consultants with the software and expertise needed for accurate, compliant railway noise assessment.

Railway Noise Calculation Methods

• Schall 03 — German federal railway noise calculation standard, widely adopted and frequently specified for major rail projects across Asia and the Middle East. Covers heavy rail, metro, and high-speed operations.
• RMR — Dutch Reken- en Meetvoorschrift Railverkeerslawaai method for railway noise assessment
• Nordic Rail — Scandinavian national method for railway noise prediction
• RailNoise — Additional railway noise calculation module
• CNOSSOS-EU railway method — European common method required for EU strategic noise mapping of major rail lines

Key Features for Rail Projects

• Train-specific emission modeling — Define emission levels for different rolling stock types (metro cars, EMUs, DMUs, high-speed trains, freight)
• Track configuration — Model ballasted track, slab track, curves, and special trackwork with appropriate corrections
• Grade and speed corrections — Apply speed and gradient effects on emission levels
• Noise barrier optimization — Automatically design barriers to achieve noise limits at receptors along the alignment
• Vibration screening — Preliminary assessment of ground-borne vibration and structure-borne noise from underground sections
• Alignment comparison — Model multiple route alignment options and compare noise impacts

Rail Noise Assessment at Each Project Stage

Railway noise assessment is required at multiple stages of a rail project's lifecycle. At feasibility, SoundPLAN is used to compare alignment options and estimate the scale of noise impacts. During EIA, detailed predictions for each alignment alternative are produced and submitted to regulators. At detailed design, barrier designs are optimized and facade insulation requirements are specified for dwellings within the noise impact corridor. After opening, SoundPLAN models can be used to verify operational noise levels against permit conditions. This multi-stage use means the initial SoundPLAN model investment delivers value throughout a project lasting many years.

Noise Barriers for Rail Projects

Railway noise barriers are frequently longer and taller than road barriers due to the geometry of train noise emission and the sensitivity of receptors close to rail alignments. SoundPLAN's barrier optimization algorithm is particularly valuable for rail projects — automatically determining the minimum height along each section of the alignment needed to achieve noise limits at every protected receptor, minimising the total barrier cost while ensuring compliance.
